What are the applications of Kohlrausch's law ?

Text Solution

Verified by Experts

Applications of Kohlrausch's law :
(1) It can be used to evaluate the molar conductivity of any electrolyte at infinite dilution or zero concentration which cannot be exprimentally measured.
(2)` wedge_(0)` for weak electrolytes can be obtained from `wedge_(0)` values of strong electrolytes involving similar cations or anions.
(3) Ionic product of water `(K_(omega))`, solubility and solubility product of sparingly soluble electrolytes can be calculated.
(4) Degree of dissociation of weak electrolytes can be calculated from `wedge_(0)` values.
